第9届北京国际电影节在京举行（英文）

The ninth Beijing International Film Festival opened on the evening of April 13,2019, with 15 movies contending the Tiantan Award prizes. The festival consistedof seven major activities including an opening ceremony, a forum and a film market.Fifteen selected films worldwide were evaluated by a jury (评委会) of seven prom-inent (著名的,杰出的) figures in the global film industry and contended for prizesof 10 categories in the festival's Tiantan Award.

Academician Glushkov and Grandmaster Fisher

In the first part of the article, the incomprehensible victories of the American grandmaster Robert Fisher over the candidates Mark Taimanov, Bent Larsen and Tigran Petrosyan in 1971 for the right to play the match for the World Chess Champion title with the former champion Boris Spassky and the victory over the champion himself in 1972 are first served as a detective story hypothesis proposed by Academician Viktor Glushkov. According to this hypothesis, R. Fisher used the prompts of a super-productive computer installed in the United States, in which a highly efficient computer chess program was played along with the matches. Communication with the computer provided a team of employees of the CIA. In the second part, the author, having reviewed briefly the history of computer chess programs, rejects the hypothesis of the academician and proposes his own.

The Aggro of "Human Nature" and "Divine Nature"

The love is the topic of the abyss of time of mankind, but inhibits in the asceticism of western religion under, the love often takes a tragedy color. In the western literature work depiction concerning the love of clergy, then there is the aggro of "human nature" and "divine nature". This text tries to explain west from three works religion bottom of love tragedy.

A review on the definitions of terms of sedimentary facies

In recent years,in some papers and manuscripts published in and submitted to the Journal of Palaeogeography(Chinese Edition and English Edition),the authors named the rocks or rock types as"microfacies"or"lithofacies",named the microfeatures in thin-sections under microscope as"microfacies",and named the macrofeatures of rocks as"macrofacies".I wrote two short papers"Words of the Editor-in-Chief—Rocks are not microfacies"(Feng,Journal of Palaeogeography 19(5):II 2017)and"Words of the Editor-in-Chief—Rocks are not lithofacies"(Feng,Journal of Palaeogeography 20(3):452–452,2018)which were in Chinese and published in the Journal of Palaeogeography(Chinese Edition).However,they did not attract much attention of readers in China and outside China.In addition,in1980 s,some Chinese sedimentologists proposed"subfacies"and"microfacies"based on the macrofeatures of rocks from outcrops and drilling cores.However,the definition of this"microfacies"is totally different from the"microfacies"proposed by foreign sedimentologists in 1940 s based on the microfeatures in thin-sections under microscope.These problems appeared repeatedly and forced me,as the Editor-in-Chief of the Journal of Palaeogeography(Chinese Edition and English Edition),to observe the policy of"A hundred flowers blossom and a hundred schools of thought contend",to write new papers"A review on the definitions of terms of sedimentary facies"both in Chinese and in English,to clarify the definitions of the terms of sedimentary facies,i.e.,"facies","lithofacies",two"microfacies","macrofacies","subfacies",etc.I hope that the new papers will attract attention of readers worldwide and they can write papers and participate in the discussion and contending of these problems,strive for getting some common understandings,and therefore promote the progress and development of sedimentology and palaeogeography.

Words of the Editor-in-Chief——some ideas about the comments and discussions of hyperpycnal flows and hyperpycnites

I basically agree with the viewpoints of Shanmugam(Journal of Palaeogeography 7(3):197-238,2018)and Zavala(Journal of Palaeogeog raphy 8(3):306-313,2019)who cited,refined and interpreted the definitions of hypopycnal flow,homopycnal flow and hyperpycnal flow.I appreciate two typical case studies of hyperpycnal flows induced by the Yellow River and Yangtze River,and the Gaoping River.The former is a normal type while the latter is catastrophic.They make up a complete knowledge about hyperpycnal flows and hyperpycnites.According to the interpretation of the word "hyperpycnal" from Greek to English,the "hypopycnal flow" should be "less density flow" or "lower density flow"("低密度流"),the "homopycnal flow" should be "equal density flow"("等密度流"),and the"hyperpycnal flow" should be "higher density flow" or "over density flow"("高密度流" or "超密度流").Some geologists called the "hypopycnal flow" as "异轻流"("abnormally light flow")and called the "hyperpycnal flow" as"异重流"("abnormally heavy flow").There are at least more than 10 names or terms about the "density flows" and the "deposits of density flows".It is a problem indeed.In addition,the density could be changed by salinity,temperature and pressure of water.Therefore,the term "density flow" may be problematic either.Another problem is that reliable and irrefutable identification markers of ancient heperpycnites are lacking.We should observe the policy of "A hundred flowers blossom and a hundred schools of thought contend" to discuss these problems and to promote progress and development of hyperpycnal flows and hyperpycnites.

Words of the Editor-in-Chief——Academic discussion is an effective measure to promote scientific development

Van Loon et al.＇s paper ＂The response of stromatolites to seismic shocks： Tomboliths from the Palaeoproterozoic Chaibasa Formation, E India＂ with a new term ＂tomboliths＂ and original viewpoints should be published, but some contents need to be discussed. Shanmugam＇s paper ＂The response of stromatolites to seismic shocks： Tomboliths from the Palaeoproterozoic Chaibasa Formation, E India： Discussion and liquefaction basics＂ pointed out some queries and problems about Van Loon et al.＇s paper. It is an academic discussion paper and should be published as well. However, some main problems, such as the new term＂tomboliths＂ and its origin of seismic shocks, ＂whether stromatolites or tomboliths are soft-sediment deformation structures or not＂, etc., also need to be discussed. Academic discussion is an effective measure to promote scientific development. The more thorough academic discussions are carried out regarding academic problems, the more scientific facts and truths will become clear. All participants in this discussion are contributors. It is active to carry out the policy of ＂A hundred flowers blossom and a hundred schools of thought contend＂ by our Journal of Palaeogeography.

Some new thoughts of definitions of terms of sedimentary facies:Based on Miall's paper(1985)

In recent years,the Journal of Palaeogeography(Chinese Edition and English Edition)continually received manuscripts,in which some authors are from China and some are from Pakistan,Lithuania,Morocco,South Africa,etc.The authors of these manuscripts,according to the viewpoint and method of Miall’s paper(1985),selected rocks from each bed in the clastic sections of their study areas and induced some rock types,such as conglomerates,sandstones and fine-grained stones,and considered them as lithofacies.It does not conform to the definition of lithofacies.I wrote some papers,i.e.,Feng(2018,2019,2020),to point out the problems and hope that the authors worldwide,especially Chinese authors,will not continually cite,spread and follow Miall’s paper(1985)viewpoint and method blindly.Prof.Miall is the first person who considered rocks(in fact,the sediments)as lithofacies and proposed a facies analysis method.His viewpoint and facies analysis method confused the definition of facies and facies analysis method.My current paper is a special article to discuss the principal problems of Miall’s paper(1985),i.e.,he considered the sediments as lithofacies and utilized lithofacies to analyze facies,but not to discuss the contributions and less strictness of architectural elements of his paper.Here,I have to declare that the facies in my current paper is the facies of sedimentary petrology,but not of other geological disciplines,such as igneous petrology,metamorphic petrology,palaeontology,stratigraphy,geophysics,geochemistry.Certainly,the definitions of facies and lithofacies are controversial.My current paper will adhere to the policy of“A hundred flowers blossom and a hundred schools of thought contend”.I hope that through academic discussions,contends and geological practice,these problems will be solved gradually.
